MS200T, 660 and 880 + Husky 385/390xp are those I remember for sure, but I believe there was at least one appearance of a larger Husky as well - there is some time since I saw the series, so memory is fading.....
One thing that surpriced me, was that they didn't seem to bring spare chain into the woods! :jawdrop:
Yeah it seems like as far away from things they are they would bring 3 or more chains. I don't see a chain being the straw that breaks the camels back on pack weight.
